Common Wrong Answers
“A calculator”
A calculator provides straightforward arithmetic answers and does not exhibit the unique behavior of a clock where time wraps around after reaching a certain point.
“A calendar”
A calendar deals with dates and months, not with the cyclical nature of time in the way that a clock does, which is essential to the riddle.
“An hourglass”
An hourglass measures time but does not involve arithmetic operations like adding numbers, which is central to the riddle's premise.
